Digital Main Board Assembly
The HEOS 'Error' occurs when the network sub-processor on the Digital Main Board fails to initialize the TCP/IP stack or maintain a heartbeat with the HEOS server. This is often caused by a failure in the flash memory where the network firmware resides or a degradation of the integrated Network Interface Controller (NIC). Replacing the Digital Main Board provides a new SoC and localized memory, restoring the handshake capability between the app and the receiver.
